Mixed chalcogen ligand complexes of trimethylplatinum(IV) halides of general type [PtXMe3(MeSRSeMe)][R =(CH2)2 or o-C6H4] have been prepared and the energy barriers associated with the pyramidalinversions of the individual chalcogen atoms measured by total band-shape dynamic n.m.r. methods. At elevated temperatures an intramolecular scrambling of all of the Pt-methyls occurs, associated with a fluxional
制备了一般类型[PtXMe 3(MeSRSeMe)] [R =(CH 2)2或o -C 6 H 4 ]的三甲基三卤化铂(IV)的混合硫族元素配体配合物,并且该能级与金字塔形的金字塔倒置有关通过总带形动态核磁共振方法测量的单个硫族元素原子。在升高的温度下,发生所有Pt-甲基的分子内加扰,这与明显影响二齿配体180°旋转的通量运动有关。
